SPECIFICATION forming part of Letters Patent No. 297,577, dated April 29, 188

(No model.)

To to whom it may concern:

Be it known that L'WILLARD D. Donn- MUS, of lVashington, in the District of Columbia, have invented a new and useful Improvement relating to Paper-File Boxes; and I do hereby declare that the following is a full and accurate description of the same.

My improvement is adapted to that class of paper-files or file-boxes wherein the papers are secured in said box by some form of clamp ing device, whereby the papers are prevented from shifting their placeor falling out if the box is turned over on its side or otherwise. Boxes of this description have gone into very general use, and in many places where they are employed it is thought desirable that they should be so attached to the shelf or other support that they may be drawn out and tilted to a position convenient for reference to the contents, and remain suspended in that position as long as desired. For this purpose such a box has heretofore been provided with a hook or equivalent, and the shelf or other support provided with a counter-hook or equivalent device,which will engage the first-mentioned hook when the box has been drawn part way or nearly off its shelf, and allow the box to tilt forward a greater or less distance, and remain attached to and suspended from the shelf. "While it is desirable that the file holder or box shall thus remain attached to the shelf, it is necessary that it may be capable of ready detachment, so that the box and its contents may, if required, be taken away for use elsewhere. All of these devices are capable of accidental detachment in the ordinary way of use-that is to say, care is required on the part of the user to insure against an accidental detachment and disaster to the box and its contents. The object of my invention is to provide against the possibility of accidental detachment without impairing the facility of intentional displacement, and,so far as I know, no file-box has heretofore possessed these features. Incidentally, the devices,whereby the box is attached to and pivoted upon the shelf are all concealed without increasing the dimensions of any member of the box, and are all within and beneath the base-board of the box, so that no partitions between adjacent Figure l is a perspective view, showing the file holder or box suspended in position for the convenient examination of the papers contained. Fig. 2 is alongitudinal section of the same. Fig. 3 is a bottom plan. Fig. 4 is a transverse section. Fig. 5 is a longitudinal section,showing way of detachment. Figs. 6, 7, and 8 represent modifications.

A is the file holder or box in suspended position for the convenient examination of the papers contained. B is an ordinary shelf. (Represented in section.) The file-box A is represented of the well-known kind manufactured by E. WV. \Voodruff, though it is evident that the particular form of the box nor the mechanism employed to hold the papers in place have no relation whatever to the improvement herein described. The under surface of the bottom board, 0, of the box A is longitudinally grooved, as at c, and the sides of said groove are undercut, so as to present overhanging flanges cl, into which the lateral extensions or T-head of the plate H may enter, slide, and be confined. These flanges d are most easily and preferably formed by means of a slotted metallic plate secured to the bottom, 0, its inner edges projecting over the margin of the groove 0, as shown. The plate H is slotted and provided with fasten ings and guiding-screws, or otherwise arranged to slide upon the shelf B without becoming detached therefrom. The T-head is slightly raised, so that it extends into the groove 0, and its lateral lugs 9 project laterally under the flanges d (I, so that said plate H cannot withdraw from said groove. At the front end, however, the flanges are cut away, so as to form an enlargement, as at '5, through which the lugs 9 may pass into and out of said groove. The range of motion of the plate H is sufficient to permit it to draw forward enough to allow the box A to tilt forward, as shown, and

push backward away from the front edge of the shelf far enough to be entirely concealed behind the front board of the box A, as shown in the figures.

It will be apparent that no detachment of the box A from the shelf B can take place except when the T-head lugs g are in the enlarge mentz' of the groove 0, when the box may be lifted 0E the said T-head; but when the box is in place on its shelf it cannot be lifted, because it is closely confined by the shelf above, and as it cannot be lifted it cannot become detached. The movement in drawing the box A forward so as to clear it from the shelf above causes the lugs g to pass within the flanges d, and thus prevent disengagement. WVhen, however, the box A has been drawn entirely out from the shelf and tilted to an angle of ninety degrees, it may then, if desired, be raised vertically until the lugs g reach the enlargement i, when it may be detached. It is impossible that this mode of detachment shall be executed except with design, unless by the rarest accident. l

By means of the sliding plate H, it will be perceived, the pivotal action is between the box A and the T-head lugs of the plate H; but the same effect may be produced by a slightly-varied arrangement, whereby the pivotal action is between said plate and the shelf. In this modification the plate K is provided with T-head lugs g, the same as plate H, and they engage in a similar undercut groove in the bottom board, e, the only difference being that said groove does not necessarily extend quite so closely to the front edge of the shelf B. In the modification the T-head of plateK is turned toward the back of the shelf instead of toward the front, and, instead of sliding on said shelf, it is pivoted orhinged to the shelf, most conveniently by means of staples driven into the shelf and incl osing a part of the end of said plate, as shown. When the box A is drawn off the shelf, the lugs 9 pass along to the inner or closed end of the groove 0, and when the box is tilted it carries the free end of the plate K with it and supports the box in the tilted position, as shown.

It is necessary,

however, to prevent the plate K from turning over too far for the proper suspension of the box, and this may be accomplished by widening the lugs, as at q, or by providing the plate K with a stop of some suitable kind, as the foot 9, for instance. The box cannot be detached from the shelf until it has been drawn out and tilted, as described, and it can only be then detached bya dead lift through a distance equal to the effective lengths of the slot 0. A combination of movements to detach the box is easy of accomplishment when desired, but extremely unlikely to occur by accident.

Having described my improvement, what I claim as new isl. A file holder or box, A, provided with undercut or flange groove 0, and a shelf, B, combined with a T-head coupling-plate, H, or its equivalent,permanently attached to the shelf B,and engaged with the flanges cl of the groove 0, so as to permit a longitudinal or tilting movement of said box without disengagement at any moment.

2. A file holder or box, A, provided below with an undercut or flange groove, 0, having an enlargement, 7', and the shelf B, combined with a T-head plate, H, permanently attached to but capable of moving upon saidshelf, the T-head lugsg of said plate being within said groove, to attach the box and shelf and be incapable of separation until said box has been withdrawn off the shelf and tilted, as shown and described.

3. The box A, provided with the undercut or flange groove 0 in the bottom 0, and the shelf B, combined with the 'T'-head plate H, fitted to enter and engage within the flanges of said groove c,and attached to said shelf, so that it may move thereon, as described, to permit the box A to move forward and tilt, as described, without at any moment being detached or detachable from said plate H.
